Speedometer Gauge
WARNING: This page is about a different car, the 2004 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
The instrument cluster uses a vehicle speed signal from the ABS/TC/IVD system to control the movement of the speedometer pointer. Vehicle speed information is sent to the ABS/TC/IVD module from all four wheel speed sensors, which is then sent to the instrument cluster by the ABS/TC/IVD module over the SCP communication network.
